5. Celine Dion

A leather-clad Celine Dion sang a medley of "At Seventeen" and "My Love" before announcing the nominees for Album of the Year.

6. Christina Aguilera

"It's fun to sing a song that has inspired me," said Christina Aguilera who performed the title song from the musical Porgy and Bess. What does the new mom sing to son Max in the privacy of their own home? I hum amp#91;a songamp#93; from the movie Mary Poppins called "Stay Awake," Aguilera (in Monique Lhuillier) said. "It's a little lullabye."

"I feel seriously under-dressed presenting these next award nominees," said Foo Fighters frontman Dave Grohl before reading the names of the contenders for Best Country Performance by a Duo or Group with Vocals. "My dry cleaner said my Nudie suit would be ready, but it wasn't."
